摘要: 利用实时红外对由光引发剂2,2',5-三(2-氟苯基)-4-(3,4-二甲氧基苯基)-4',5'-二苯基-1,1'-二咪唑(WJ-HABI)、增感剂4,4-二(N,N'-二甲基氨基)苯甲酮(EMK)及供氢体N-苯基甘氨酸(NPG)组成的复合引发体系进行光聚合动力学研究.探讨了复合引发体系的浓度、不同配比、紫外光的强度及不同官能度单体等因素对光聚合动力学的影响.结果表明,增感剂(EMK)的加入能使WJ-HABI复合体系的紫外吸收波长向长波移动;随着引发体系浓度的增大、紫外光强度升高,双键转化率及聚合速率增大,且聚合体系达到最高转化率所需时间越少.

Abstract: The photopolymerization kinetics of combination photoinitiator systems which were composed by 2,2',5-tris(2-fluorophenyl)-4-(3,4-dimethoxypheny)- 4',5'-diphenyl-1,1'-biimdazole(WJ-HABI), photosensitizer N, N-bis(diethylamino) benzophenone (EMK) and hydrogen donors N-pheylglycine(NPG) were investigated by Real-time Infrared(RT-IR) spectroscopy. The different initiator concentrations, the different compositions of photoinitiator systems, light intensity and different functional monomers on the polymerization were studied. The results indicated that with the increase of initiator concentration and light intensity, the double bond conversion and the polymerization rate increased.

Key words: photopolymerization kinetics, photoinitiator, photosensitizer, hydrogen donors, RT-IR
